M91: Juvenile osteochondrosis of hip and pelvis
M91.2: Coxa plana
The two hip joints connect the pelvis to the thighbones (femurs). At each side of the pelvic bone there is a depression. This depression is also called the hip socket. The femoral head sits in the hip socket. The femoral head is the rounded, top end of the femur.
Bone tissue can die off if does not get a good supply of blood. If bone tissue has died off, the affected bone may become misshapen. If the femoral head becomes misshapen, it can be painful. You may be unable to move your leg so well.
